If the meaning of terms like ''form-based code,'' ''transects'' or ''transportation demand management strategies'' still elude you, take note.

On Saturday, Miami planners will hold an open house at Legion Park that aims to shed light on such zoning-related terms. Forum organizers plan to answer questions that residents and others may have about Miami 21, the city's sweeping effort that plans to revamp what some describe as an antiquated zoning code.

Starting with the city's development-crazed ''eastern quadrant,'' neighborhoods from downtown to the Upper Eastside could be rezoned to allow for a more pedestrian-friendly setting, complete with tighter roads and shady trees -- the hallmarks of the New Urbanism movement. The Miami 21 plan also encourages setbacks, which create smoother visual transitions between high-rises and single-family homes.

The Saturday open house comes amid some residents' concerns that they haven't received enough information on the project -- or been able to give their input on individual zoning codes for their neighborhoods.

''We've been begging for this,'' said civic activist Allyson Warren, referring to Upper Eastside residents' request for a public meeting.

In an effort to reach out to different neighborhoods, the city has held meetings.

It also solicits feedback through its website, Miami21.org.

To date, the Miami 21 plan is behind schedule.

The item was expected to be adopted in October but is likely to head to the city commission for approval before year's end.

A spokeswoman for the city's planning department has said the department will be seeking public input for at least another month or two.

The Saturday meeting, scheduled from 8 a.m. to noon, will be held at Legion Park, 6447 NE Seventh Ave.
